Boiler Replacement in Vancouver
Old boiler letting you down? We replace failing units fast with high-efficiency modern systems.
Boilers don't give much warning before they fail. A heat exchanger crack, a failed ignition board, or a seized circulator pump can leave you without heat on the coldest morning of the year. When your boiler is past its useful life or the repair cost approaches the value of the unit, replacement is the smarter call.
We replace boilers across Greater Vancouver fast. Our technicians carry the most common replacement units on hand, coordinate permits same-day where possible, and work efficiently to restore heat with minimal disruption. We remove and responsibly dispose of your old unit as part of the job.
A boiler replacement is also an opportunity to upgrade. Replacing an 80% AFUE mid-efficiency unit with a 95%+ condensing boiler can meaningfully reduce your gas bills. Adding zones, upgrading to modulating-condensing controls, or expanding to include radiant floors are all practical during a replacement.
What Boiler Replacement Involves
Boiler Assessment & Sizing
Before selecting a replacement unit, we assess your existing distribution system. If your baseboards or radiators are sized for a higher water temperature (older systems often run at 180°F), we evaluate whether low-temp operation with a condensing boiler is feasible, or whether setpoint adjustments are needed. A properly sized replacement runs at lower temperatures and higher efficiency.
Old Unit Removal & Disposal
We disconnect and remove your old boiler safely. Gas lines are capped properly during removal. Old units are disposed of through appropriate channels — they're not left on your curb or dumped. We handle the whole removal.
New Boiler Installation
The new unit is installed on the same pad or a new wall mount, connected to existing piping where reusable, with new sections where the old connections are compromised. We upgrade the expansion vessel, pressure relief valve, and air separator if the existing components are past their service life.
Controls Upgrade
Modern replacement boilers include advanced controls that older systems lacked. We configure outdoor reset (which adjusts boiler water temperature based on outdoor conditions — the single biggest efficiency gain in hydronic heating), domestic hot water priority, and integration with your existing thermostat or smart home system.
Pressure Testing & Commissioning
After installation, we pressure test to 1.5× working pressure, bleed all air from the system, verify zone operation, perform a combustion analysis, and commission the controls. The system is running and tested before we leave.
Technical Details
Condensing boilers achieve maximum efficiency at low return water temperatures (below 55°C/131°F). Existing baseboard systems designed for 82°C/180°F supply often need setpoint recalibration or additional baseboard footage for condensing operation to be fully effective.
Most residential boiler replacements in BC must be reported to the BC Safety Authority within 10 days if they involve gas connections. Our technicians handle this notification as part of every job.
Replacing a boiler is an opportunity to inspect and clean the entire system, including the distribution piping, zone valves, and baseboards. Sludge in older systems accelerates heat exchanger corrosion in new boilers — we often recommend a system flush on replacement jobs.
Wall-hung combi boilers require adequate gas supply pressure — verify your meter capacity if replacing a floor-standing unit with a wall-hung unit with higher BTU input.
We check flue gas CO levels with every replacement commissioning. CO levels above 100 ppm (air-free) in a new installation indicate a combustion problem that needs immediate resolution.
